To all 'ivh ow z it); ay colicern:

Be ,it known that we Lnw s L. Roonas and (All ster C. Romans, citizens of the, United States, and residents of Orange, in,

the countyof Franklin. and State of Mas- I sacluisetts, have invented certain new and useful. improvements in Sheet-Gages for Printing-Presses, of which the following is a specification. e

This invention relates to a sheet-gage. for

a printing press, and particularly toa sidegage for' a one-cylinder, two-revolution press in which thecylinder is morable-u'p down relatiy ely to achorizontally re-i ciprocating form and bed; and theprincipal object of the invention is to provide a gage and especially a side-gage, which is automatically movable to its working posisun for locating an edge of a sheet to be, printed, this inovement being preferably controlled by an element of the press itself, and, in the case of a one-cylinder, two-'reso hition press, usually by the rise of the cylinder of the press. v y .A'Ifurther important feature of the invention is an automatically movablegage which is automatically shiftable away from the. surface of a sheet and its supportusually the feedrtable-for the purpose of releasing the sheet when the gaged edge thereof is in readiness for engagement by the usual gripping means of the press. In connection with this movement of the gage one feature of the invention relates to means for actuating the gage in proper timing with the grippin'g'means of the press.

Other features of the invention not here inbefore referred to will be hereinafter described andclaimed and are illustrated in the accompanying drawings, in which Figured is a plan of a portion of one type of printing pressto wit, a one-cylirider, two revolution press-embodying ages "constructed in accordance with this $5 invention"; Fig. 2 is a sectional elevation of I the ifront side of the same; Fig. 3 is an en larged detail illustrating in elevation and longitudinal section the construction ofone of side-gages, its operating means and certain parts with which it coacts, showing the cylinder up and the gage forward and beginning to rise to clear a sheet; Fig." 4 a similar View sho'witig the cylinder farther down and the gage in position and back,

A" suitablebase plate is illustrated at 2, Being 'suppoiited on the main fixed frame of the press in-sucli a manner aspto permit the inovementefthe gage proper toward and *fronr its orking" position. It also supported on said" frau e-work in such a manner iasltoiperrnit another movement of the gage,- whichnnove-l ment will be'hereinafter described f The gage proper may be substantihlly or the usual type employed inprin'ting for gaging the edges ofsheets fed b to the machine, it being; indicated heife in at Cooperating therewithisalso the usual spring tong the proper delivery of a-fsheet'with its edge fiat. Both the gage properand th'is'tongu'e or guard are in this case carried by and rs movably secured to-a gage-rodffi, adjustable back 1 and forth with fre'sp'fec a0 ,ths maia' uo frame or base-p1ate 2 of the". aga' stidrrod being supported directly inn; tubular 'i'nem-j ber 6, to slide therein a's' adjnsted,- and the tubular member being mounted in 'bearihg'sg i mend Presses' 5 in} uprights; '7 and f8. rising from 'the base 10;

working or gaging position}; Snitable i-nean's' 3 11' are employed for limiting the return movement of the gage-rod and the gage, a stop being provided for determining the position of these parts on said'return stroke. This stop is shown as formed on a cross-head, 10, mounted on the forward end of the tubular member 6 in posit-ion to engage the forward end of the riser S and be stopped thereby on the return stroke of the gage, as shown in Fig. 4. This cross-head 10 is also shown as having a depending lug, 11, with an opening in it to'permit it to 'sl ide'back andforth on a guidel2, projecting from the forward end of the'base-plate 2, this construction serving to hold'the' cross-head positively against turning movement on the tubular member 6while at the same time allowing it to slide freely thereon.

' The gage-rod 5 should also have a suitable'adjustment for controlling the positions of the gage proper 3 and the tongue or guard 4 with respect to the edge of a sheet.

I In the present case this adjustment is controlled by a threaded rod, 13, in fixed relation withthe'rod 5 and extending through an opening- 14, in the upper part of thecrossheacl, and also by a pair of knurled adjusting and check nuts, 15 and 16, mounts ed on the threaded rod 13 and cooperative therewith and with the adjacent cheeks of the upper part of the cross-head 10 in a manner which will be clear. By suitably adjusting the nuts 15 and 16 the gage-rod, the'gage and the'guard may be shifted to any desired adjusted position and held there the desired fixed relation to'the tubular member 6. r

, Normally the parts just described, to wit, the gage, the guard, etc., will'preferably be held in the relation to the base-plate 2 that is'illustrated in Fig. 4, a spring, such as 17, being illustrated as working between the "riser18 of the base-plate and a suitable stop, suchas 18, on the tubular member 6 for the 'jpurpose of normally retracting the gage, etc],- to this position. 'lVhen the gage is to be shifted forward to its working or gaging ,position this will be effected by suitable automatic means, the power exerted by which is superior to that of the spring 17;

The movement of the gage and other parts cooperative therewith to a forward o-r"wor king position may be automatically brought about at the proper time by any suitable means carried by a printing press. When the gage is used ona hand-fed printing press of the one-cylinder, two-revolution type specifically illustrated in the drawings, in which a cylinder such as C, reciprocates up and down to permit the passage of a form, f, and a reciprocating bed, I), under it, this forward movement of the gage to its working position will preferably be controlled by the rise of said cylinder. In the construction specifically illustrated this working proper time. This automatic means also embodies in'the construction illustrated a cam and a cam-actuator one of which is carried by the gage and the other mounted to move up and down with said'cylinder and pressrod. Here the cam-actuator is secured to r the press-rod and the cam is attached to the gage, said press-rod havingthereon a plurality of collars, 20, one for each of the sidegages employed and each carrying preferably an antifriction roller or cam-roller, 21, journaled in lugs, 22, projecting from the collars 20'and in position'to cooperate with suitable cams carried by the ages. .Each of these collars is also prefera bly shiftable or adjustable to any desired position lengthwise of the press-rod l9 and when in the position desired is held there, as by a set" screw, 23. The cam carried by the gage may be of any proper type for effecting the desired movement of the gage and other parts, but in order that it may cotlperate with its actuator, the cam-roller 21, under all conditions, and particularly when the gage,is shifted transversely to and away from ,the sheet gaged by it, as'will presently be described, it is preferable to make it as shown in the drawings, that is, with a working face substantially concentric with the axis of a fixed press-rod, 24, on which the gage is directly mounted. Here this cam is shown as embodied in a bent-rod, 25, one end of which is inserted in the rear end of the tubular member 6 of the gage and is securely held in place therein, as by means of a setscrew, 26, passing through a boss forming the stop 9. It will be seen that the cam is also adjustable, its forward end being shiftable to different positions'in the tubular member 6 in any of which it may be clamped and'held by said set-screw 26. Inany. of the positions to which it may be set this cam is substantially concentric with the axisof the pressrod 24 and in any of these positions'fiit will cooperate properly with the roller 21 and will permit th lifting of the gage from the sheet. The manner in which thislifting movement. is preferably accomplished will now be described.

The gage and all its parts will usually have, in addition to the reciprocating, subs'tantially horizontal movement before described, a movement transverse to a sheet gaged by it, this movement being, in the con- I s'truction illustrated,- an oscillatorylonerabout the. axis of'the 'pressrod'24y This rod is mounted-in suitable bearings at opposite.

sides of the press for? rocking movementand to 1t are, secured .a rnumber of gages corre- When fastened in place on the rod 24 each occup'ied by these ga'ge r constitutes a rock-armthat rocks with ithe'ro'd or =s'haf-t'24., The rocking movement of this rod 24 may be controlled automati cally by any: suitable means on the press.

In this case the oscillation of fireside-gages S is intended to'be' efl'ected in proper relation with the operation) of. the gripping '20 means; the'meansemployed for imparting movement to the devices for actuating the grippers being also illustrated as used :to impart movement-to the devices for rocking,

the shaft, 24., At'one end thereof this shaft is shown as having a rock-arm, 29, which is "intended on the. press'rod: 19 and movable up andt,o be raised by an arm, 30, pivoted down 'therewith, and cooperating at its for- ;ward end with'a' cam, 31-, in fixed relation with a gear-wheel, :32,,driven by a pinion,' *33, secured to the shaft of the cylinder 0.

Through'thes e'connections thecam 31 rotates in proper timing to'the revolutions of the cylinder C. fiThedottedline positions of theiparlts, shownin" Figs. 2' and 3 and also in FigJ4, show: the rock-arm 29 and the swinging arm- '30 in'the positions they occupy when. the ga *is'downandin position to cooperate w he side ofa sheet. The dot and dash lines in "Fig. 3 show the Y positions arts when the rock-arm 29 is' raised to'oscifl the surface of a sheet to permit the engagement of such sheet by thegrippers.

As is usual, he'gear-wheel 32 also has in fixed relation therewith a cam, such as 34, controlling thethrow'of the gri pers. The grippers themselves may be 0 the usual type, as indicated at 35, and mounted on a rock-shaft, 36, revolving withthe cylinder C. At one end thereof this rock-shaft carlies a cam-segment, 37, cooperative with an actuating pin, 38, mounted at the upper end of the main frame and havln under side of its outer end a groove in which works the edge of a cam wheel 34. This pin is reciprocated by said cam-'wheel'at the' proper times in the usual manner to cause the grippers 35 to engage the forward side of a sheet,Ls-,. on the eed table, so that the to'thev pointof impression and properly printed -'.a'ftorthe form has been inked bythe means,- suchas the ink-roller z.

The cam 34- which controls the pin -38:

ate the gage away from.

at the may also serve to operate,-through a suitable .connection such as a lever, 39, an automatically movable element, 40, of an end gage, E, having a gage face, 41-, notautomatically' movable, for effecting a preliminary"' gaging of the end of a sheet, gages, such as 42, cargager'nent ofthe gaged sheet by the grippers 35. The specific features of theen'd-gage E 'and the means for operating-the same constit-ute no part of this invention but form the subject matter of a companion application, Serial No. 712,621, filed August 1, 1912, and are described in detail therein.

In operation, a sheet, 8, is'fed, usually by hand, on to'th'e feed-table and is engaged by the end stop 41 and is also broughtat its forward side into position to be engaged by the side-gages 3. It being understood that the-cylinder C is rising after having finished itsp'rinting revolution the rollers 21'come into contact with the cams 25 at the proper point in the rise of the cylinder, and move theside-gages 3- forward to push the sheet 8 automatically into place on the feed-table and gage the side of the sheet. At substantially the same time, and in advance of the operation of the grippers, the end-gage faces 42 of. the'end-gage E are shifted automatically forward to push the rear end of the sheet into place and age it. Thereupon the cam 34 operates in t e usualmanner to actuate the grippers 35 to engage the forward end of the sheet on the feed-table and at substantially the same time the cam 31, operating through the swinging arm 30 and the rock-arm 29, oscillates the side-gages. and

they begin to rise to clear the gaged sheet. On the descent of the. cylinder to. e fi'ect another impression the side-gages are drawn back by their springs 17 to the position shown in Fig. 4 and remain in that position-until another sheet is in position to be gaged. At the same time the side-gages descend owing. to the withdrawal of the cam 31 from the end of the swinging arm 30. What we claim is:
